Mumbai, Nov 27 (IANS) Kareena Kapoor played a sex worker in "Chameli" and does so again for "Talaash", a role she describes as amongst her most sensitive and powerful.

"I play a prostitute, who is kind of an escort. It's a very deep character. I have hopefully achieved a sensitive performance. It's by far one of my most sensitive performances, I believe," Kareena told IANS ahead of the release of "Talaash" this Friday.

Her role in "Chameli" cannot be compared with what she has portrayed in "Talaash", says Kareena, who will be seen sharing the screen with Aamir Khan and Rani Mukerji in the thriller.

" 'Chameli' was totally different. It was very raw. The lingo and the language, body language and the outfit - everything was different. Here from head to toe, the performance, and everything is different," she said, adding that she signed on the dotted line for "Talaash" because it allowed her to work with Aamir again.

"I don't look at the project with commercial aspect. I wanted to work with Reema (Kagti) and wanted to work with Aamir again. I loved the role that was offered to me. This is one of the most powerful roles that I have done," she said.

"Reema comes across as a very strong director and a strong personality, but when you get to know her, she is a very sensitive girl and that is what she has brought about in her actors and in her film," Kareena said about her director.
